359649 The depth ' \(d\) ' at which the value of acceleration due to gravity becomes \(\dfrac{1}{n}\) times the value at the earth's surface is (\(R=\) radius of earth)

1 \(d=R\left(\dfrac{n}{n-1}\right)\)
2 \(d=R\left(\dfrac{n-1}{2 n}\right)\)
3 \(d=R\left(\dfrac{n-1}{n}\right)\)
4 \(d=R^{2}\left(\dfrac{n-1}{n}\right)\)

359650 Assertion :
A body becomes weightless at the centre of earth.
Reason :
As the distance from centre of earth decreases, acceleration due to gravity increases.

1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Assertion is incorrect but reason is correct.
